A capacitor stores electrical energy in an electric field between two conductive plates separated by an insulating dielectric. Capacitance C (farads) measures how much charge Q is stored per unit voltage V: C = Q/V. Capacitors are used in power supplies for smoothing, in filters, timing circuits, and energy storage (supercapacitors).

دليل خطوة بخطوة

  1. 1Q = CV (charge = capacitance × voltage)
  2. 2Energy stored: E = ½CV² (joules)
  3. 3Capacitors in parallel: C_total = C₁ + C₂ + ...
  4. 4Capacitors in series: 1/C_total = 1/C₁ + 1/C₂ + ...
  5. 5RC time constant: τ = RC — time to charge to 63.2% of supply voltage
